Bill C and Bob L, I agree that back issues are valuable resources, but have had trouble researching which ones address my specific needs. May I suggest that the PB site develop a more detailed index of articles and search options of those back issues? You may want to look at posting articles with a payment required to download - that would be a way to expand revenues without having the physcial handling of the paper versions. (Of course, PB subscribers would get a discount, right?) While I recognize that there would be initial development costs, the long term maintenance costs should be minimal. Even as a PB subscriber, there is no question I would be willing to "buy" such downloads!
PS - Bob, congrats on your new position!!!
